Value Collection C89399 M3 Flat Washer Zinc-plated 100-pack

Product Description

The VALUE COLLECTION C89399 is a standard flat washer designed for M3 metric fastener applications. Made from steel with a zinc-plated finish, this washer measures 3.2mm inside diameter, 7mm outside diameter, and 0.5mm thick. It distributes load across the bearing surface of an M3 screw or bolt, reducing the risk of fastener pull-through and surface damage. Each package contains 100 washers. This hardware is appropriate for mechanical assembly, light fabrication, HVAC panel work, electrical enclosure assembly, and general trade use wherever M3 metric fasteners are specified.

These M3 flat washers are suited for residential and commercial applications requiring metric fastener hardware. Common install scenarios include equipment panel assembly, control box construction, and sheet metal work where M3 screws are used. The zinc-plated finish provides a basic level of corrosion resistance for indoor and moderate-exposure environments. Conformance to DIN 125, ISO 7089, and ISO 7090 standards makes these washers appropriate where fastener standard compliance is specified in engineering or procurement documentation.

Installation Notes

Install using standard hand tools appropriate for M3 metric fasteners. Ensure mating surfaces are clean and free of debris before seating the washer. Zinc-plated finish is intended for dry or low-humidity indoor environments; consult material specifications before use in high-moisture or outdoor applications. No special trade license is required for fastener hardware installation, though follow applicable mechanical or electrical codes when assembling equipment enclosures.
